Description

Technical Field

[0001] The utility model belongs to the technical field of tunnel construction, and particularly relates to a tunnel construction vault deformation monitoring device. Background Art

[0002] Safety is the top priority in tunnel construction. The most dangerous source comes from the deformation or collapse of the tunnel vault. Accidents occur quickly, leaving little time for personnel to react, and can easily cause serious casualties.

[0003] Therefore, during the tunnel construction process, it is necessary to monitor the tunnel vault in real time to determine whether the tunnel vault is deformed and whether it will cause tunnel collapse.

[0004] At present, tunnel vault monitoring mostly uses electronic equipment for scanning, and determines whether deformation has occurred through reflected signals. However, this method cannot intuitively show the pressure generated at the deformed position, and can only be judged by the deformation amplitude. There is a certain lag in the possible harm that may occur later. Because when the deformation accumulates to a certain extent, it often only takes a moment to cause an accident, so it is meaningful to measure the pressure generated at the deformed position. Utility Model Content

[0008] Furthermore, the support column includes a fixed column and an adjusting column threadedly connected inside the fixed column, and the adjusting column is coaxially arranged with the fixed column.

[0009] Furthermore, the fan-shaped support plates are arranged at intervals.

[0010] Furthermore, a filling block is provided on the fan-shaped support frame, and the filling block is adapted to the gap between the fan-shaped support plates. A telescopic rod for inserting the filling block between the fan-shaped support plates is provided between the filling block and the fan-shaped support frame.

DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments.

[0023] It should be noted that the terms used herein are only for describing specific embodiments and are not intended to limit the exemplary embodiments according to the present application. As used herein, unless the context clearly indicates otherwise, the singular form is also intended to include the plural form. In addition, it should be understood that when the terms "comprise" and / or "include" are used in this specification, it indicates the presence of features, steps, operations, devices, components and / or combinations thereof.

[0024] Example 1

[0025] like Figure 1-Figure 3 As shown, a tunnel construction vault deformation monitoring device comprises a door frame 1, a fan-shaped support frame 2 installed on the door frame 1, a support column connected to the fan-shaped support frame 2 in a fan-shaped sliding manner, a fan-shaped measuring platform 4 installed in the fan-shaped support frame 2, and a fan-shaped support plate 5 fixedly connected to the outer end of the support column, and a weight sensor 6 corresponding to the support column is installed on the fan-shaped measuring platform 4;

[0026] The door frame 1 is door-shaped, and the fan-shaped support block, the fan-shaped support frame 2 and the fan-shaped measuring platform 4 are all fixedly connected to the upper end of the door frame 1 and the two are coaxial;

[0027] In order to avoid hard contact between the support column and the weight sensor 6, a buffer pad 14 is installed between the support and the weight sensor 6. The support column includes a fixed column 3 and an adjustment column 7 threadedly connected in the fixed column 3. The fixed column 3 and the adjustment column 7 are coaxially arranged. The fixed column 3 is fixedly connected to the buffer pad 14, and the adjustment column 7 is rotatably connected to the fan-shaped support plate 5.

[0028] In this embodiment, the fan-shaped support plates 5 are arranged at intervals;

[0029] In this embodiment, a controller 12 and an indicator light 13 are installed on the door frame 1 , and the indicator light 13 and the weight sensor 6 are both connected to the controller 12 .

[0030] Working principle: after the tunnel is excavated, by moving the door frame 1 into the tunnel and rotating the adjustment column 7 to make the fan-shaped support plate 5 abut against the tunnel vault, the weight sensor 6 is squeezed by the support column and transmits the weight signal to the controller 12. The controller 12 starts to monitor the signal transmitted by the weight sensor 6. When the value transmitted by the weight sensor 6 is greater than the preset value in the controller 12, the control indicator light 13 flashes to remind that the tunnel vault is deformed. By setting the values ​​in the controller 12 in multiple layers, different degrees of deformation can be warned.

[0031] In combination with the above, the present application supports and monitors the vault in the tunnel by setting up a door frame 1, a fan-shaped support frame 2, a fan-shaped measuring platform 4, a support column and a weight sensor 6. The data transmission is fast and accurate, and different degrees of monitoring and early warning can be performed, which effectively solves the problem of lag in the current use of electronic equipment to monitor the tunnel vault.

[0032] Example 2

[0033] like Figure 1-Figure 3 As shown, the structure of this embodiment is roughly the same as that of embodiment 1. This embodiment is further optimized on the basis of embodiment 1. In this embodiment, in order to avoid excessive pressure on the fan-shaped support block after deformation occurs, which causes the fan-shaped support block to lose its function, a filling block 8 is installed on the upper fan-shaped support frame 2 in this embodiment, and a telescopic rod 9 for inserting the filling block 8 between the fan-shaped support plates 5 is installed between the filling block 8 and the fan-shaped support frame 2. In this embodiment, the telescopic rod 9 is an electric cylinder, and the electric cylinder is connected to the controller 12. When the controller 12 detects that the pressure of the tunnel arch on the fan-shaped support block is too high, the controller 12 controls the telescopic rod 9 to extend and extend the filling block 8 between the two fan-shaped support blocks. The filling block 8 is set to form an arch between the fan-shaped support blocks, and the extrusion force between the fan-shaped support block and the filling block 8 is used to improve the overall load-bearing capacity and avoid collapse.

[0034] In order to prevent the filling block 8 from being displaced under the squeezing of the two fan-shaped support blocks, elastic rubber pads 10 are fixedly connected to both sides of the filling block 8 close to the fan-shaped support blocks. The rubber pads are provided to increase the bonding force between the filling block 8 and the fan-shaped support blocks.

[0035] Example 3

[0036] like Figure 4 As shown, the structure of this embodiment is roughly the same as that of embodiment 2. This embodiment is further optimized on the basis of embodiment 2. In this embodiment, filling grooves 11 are provided on the fan-shaped support plate 5 at intervals. The filling grooves 11 are parallel to the axis of the fan-shaped support plate 5. By opening the filling grooves 11, during later repairs, a supporting object with stronger load-bearing capacity can be passed through the filling grooves 11 to replace the original supporting columns, thereby facilitating repairs of the deformed positions.
